My Pi 3 hanged because of overheating. It happened for the first time. I am on LibreElec 8.0.1. The Pi is located in a case with heatsinks as well as ventilation holes. The temperature around Pi 3 is about 21C.
As it happened for the first time I don't know how much it is connected to LE.
Did you experience this?
No.
What is your processor temperature when Pi is idle?
At what percentage run your processor cores when Pi is idle?
What are your overclock settings, if any?
Did you get an icon in the top right corner of the screen?
If not, it's not overheating.
Ventilation holes and heatsinks does not equal to ventilation. You will need some form of active airflow via a (small) fan.
Same as with external HDDs overheating in their cases.
I always thought the icon in the top right, be it a rainbow square or a lightening bolt related to low voltage from the psu?

AFAIK...
rainbow square = not enough power (Amps)
lightning bolt = not enough volts
full red square = overheating
Awesome, thank you for the info klojum
All the best

Yes, the icon is there.

When it's idle it's 45-47C.
Cpu utilization is about 12-14%.
It's not overclocked.
These are values similar to mine, and mine never overheats. What was Pi doing when it overheated?

Nothing, just running Kodi. No movie was beeing watched.

This is different from the rainbow square which always appears in the center of the screen when (cold?) booting, correct?
I run my Pi 3 in a Flirc case - the entire case is basically the heatsink as there is a finger molded into the case which thermally couples the FPGA/CPU with the case. Mine typically runs around 40-41 C when idle.

Current pi firmwares show a thermometer in the top-right corner when thermal protection kicks in, and even then the pi is capable of running at very high temperatures for an extended period. In other words, if you didn't see the thermometer and it wasn't insanely hot (which is unlikely in a case with heatsinks etc.) the hang was probably software induced and not related to heat.

Could you share the link showing this case?
Thanks mate!
